Graphite and special lubricants are evenly dispersed in its entirety in this type of Polikim's cast polyamide. The material is dark grey colored. Kestamid-GRF^® has a high degree of crystallinity and better hardness and compression strength properties compared to standard Kestamid^®. It has a low coeffient of friction and a high degree of abrasion resistance. It has good weatherability and UV resistance properties and can be more easily mechanically machined compared to standard Kestamid^®. It also can be used in higher temperatures compared again to the standard type.
